TOP
PAA-1800 series products adopt a double-layer cast aluminum plate structure, which is not easily deformed after long-term high temperature use and has good heat dissipation; The graphite furnace method for light controlled heating can directly monitor the temperature of the inner wall of the graphite tube: the step precision 0.005nm wavelength precision screw drive increases the accuracy and repeatability of the instrument wavelength; Deuterium hollow cathode lamp buckle background, long service life. Abnormal automatic alarm, automatic system shutdown, and automatic power-off can save measurement data.
High precision fully automated optical system
A large-area grating with a dispersion rate of 1800 lines per millimeter, a new self collimating monochromator, and all lenses are coated with quartz. The wide detection range and optical stability ensure the accuracy of analysis. The fully automatic 6-lamp holder is equipped with six independent lamp power supplies, which can be preheated separately.
Polymer Atomization Laboratory
Polymer material corrosion-resistant atomization chamber, acid and alkali resistant, including hydrofluoric acid, can achieve good sensitivity and stability in both organic and inorganic solutions.
Titanium burner
Optional 50mm and 100mm burners, air-cooled premixed type, corrosion-resistant, high salt resistant, greatly improving flame efficiency and flame analysis accuracy
Fully automated analysis
It can automatically complete safe ignition, extinguishing, and switching, with a reliable structure and low failure rate, thus ensuring the sensitivity and reproducibility of the flame method. The lamp position platform automatically switches, and high-performance hollow cathode lamps can be directly used to improve the sensitivity of flame analysis. The power supply parameters and beam position are automatically adjusted, and the wavelength scanning and peak finding are fully automatic
High tech indicators
The element testing sensitivity of PAA-1800 atomic absorption spectrometer has reached the advanced level in the industry, with a sensitivity of ≤ 0.015ug/mL/1%; Baseline drift less than 0.003Abs/30m, stability better than 0.005Abs/4h
Background correction system
The use of tritium hollow cathode lamp and self absorbing buckle background for background correction eliminates the interference of molecular absorption during low content determination, reduces the emission noise of the lamp, prolongs its service life, and has good stability. When the background signal of the deuterium lamp is 1A, the background subtraction ability is greater than 50 times
Intelligent analysis
Very intelligent, user-friendly design, automatic setting and adjustment of flame height, automatic ignition, automatic optimization of horizontal position, and system automatic setting of gas flow rate. In case of power outage, misoperation, acetylene leakage, etc., the system will automatically activate the safety protection function
